Wells Score PE Calculator
Wells Score PE Calculator for Hematology. Use the score to guide D-dimer, imaging, or treatment pathways in suspected pulmonary embolism according to local protocols.
How this calculator works
The Wells PE score estimates pretest probability of pulmonary embolism from clinical findings, risk factors, heart rate, hemoptysis, malignancy, and alternative diagnosis likelihood.
Inputs used
- Clinical signs of DVT
- Alternative diagnosis likelihood
- Heart rate
- Immobilization/surgery
- Prior VTE
- Hemoptysis
- Malignancy
Clinical interpretation
Use the score to guide D-dimer, imaging, or treatment pathways in suspected pulmonary embolism according to local protocols.
Limitations and safety notes
Clinical judgment overrides the score in unstable patients, high-risk presentations, pregnancy, active anticoagulation, or when PE is strongly suspected.

Editorial review and citation methodology
Reviewed by the Quick Medical Calculator Editorial Team. Last reviewed: June 19, 2026. The review checks calculator inputs, intended population, interpretation, limitations, and source alignment.
- Prefer original validation studies for scoring systems and prediction tools.
- Use current specialty society guidance, transplant allocation policy, public health guidance, or regulator resources when they govern clinical use.
- Include limitations and safety notes when a calculator is population-specific, context-dependent, or unsuitable as a standalone decision tool.
